PIE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 744,638, dated November17,1903.

Application filed August 31, 1903. Serial No.1'71,358. (No DlOdBl- J Toall whom, it may concern:

Be it known that I, HENRY H. SPRING,a citizen of the United States ofAmerica,and a resiis trimmed off even with the edge of the pie-.

plate by one or more rotating and orbitallymoving trimming rollers orheads, and has for its object to provide a simple and efficientstructural arrangement and combination of parts adapted to perform suchmarginal trimming of the pie-crust without liability of adhesion of thecrust to said rollers and without liability of tearing such crust.

In the accompanying drawings, illustrative of the present invention,Figure 1 is a vertical sectional elevation of a pie-making machineembodying the present improvements. Fig. 2 is an enlarged detail sectionof one of the orbitally-moving trimming-heads and the gearingconnections forimparting rotation thereto during its orbital travel.

Similar numerals of reference indicate like parts in both views.

Referring to the drawings, 1 represents the supporting-frame of anyusual and suitable construction, and which is provided with anupwardly-extendin g and forwardly-overhanging bracket 2, in which isjournaled the operating mechanism of the present invention, ashereinafter more fully set forth.

3 is a tray or carrier for the" reception of the pie-plates and thepie-crusts imposed 1 thereon and adapted to carry the same between thetrimming-rollers, hereinafter described. ment in the supporting-frame 1in any usual and suitable manner. In the construction shown the carrieris secured at the upper end of a vertically-sliding guide rod or bar 4.,to which movement is imparted by a foot lever or treadle 5 and anintermediate flexible connection 6, passingover a sheave 7, as shown.

8 is a horizontally-arranged bevel gear or annulussecured in astationary manner to the bracket 2 of the main frame and in a Suchcarrier has vertical move-v position concentric with a vertical axialline passing through the aforesaid carrier 3.

"9 is a horizontal flier or spider arranged gears, by which rotarymotionis imparted to the trimming heads or rollers of the present invention,as hereinafter more fully described.

12 is a horizontal driving-shaft journaled on the upper end of thebracket 2 and having operative. engagement with the flier-shaft bymiter-gears 13 or other equivalentconnectiou.

14 represents the trimming heads or rollers, which in the presentinvention are of a segmental spherical form, as shown, and which arejournaled in a horizontal plane in the pendent arms 11 of the flier 9 byhorizontal shaft 15, so as to be capable of rotation upon their axis.

16 represents pinions secured to the outer ends of the shafts 15aforesaid, and 17 represents intermediate or idler gears journaled onthe armsll of the flier 9, as shown, and each of which is formed with astraight-gear portion 18, gearing with an individual pinion 16aforesaid, and a bevel-gear portion 19, gearing with thebefore-described stationary bevel-gear 8.

With the described arrangement and with a revolution of the flier 9 in ahorizontal plane the stationary bevel-gear 8 will cause a revolution ofthe intermediate gears 17 as the same move around the gear 8 in anorbital path.

Such intermediate gears 17 in turn impart 110- I tation to the pinions16 and to the trimming heads or rollers 14, so that said trimmingheadswill in the practical operation of the mechanism have a combined orbitaltravel and a rotation upon their own axis.

From an extended practical trial it has been found that the sphericalform of thetrimming-rollers and their arrangement in a horizontaldirection with relation to the vertically-moving carrier or tray 3,which carries the pie-plate and imposed pie-crust to be trimmed, affordsa very efficient structural combination of parts, in which all danger oftearing the pie-crust'is avoided and a very perfect trimming operationeffected in a continued use of the apparatus.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a pie-nr1akin;., machine of the character herein described, thecombination, of a supporting-frame, a reciprocable pie-plate carrier,revoluble trimming-heads arranged with their axis of revolution atsubstantially right angles to the line of reciprocation of said carrier,and means for imparting orbital and rotary movements to saidtrimmingheads, substantially as set forth.

2. In a pie-making machine of the character herein described, thecombination of a supporting-frame, a reciprocable pie-plate carrier, aflier journaled to have rotation in a plane above said carrier,revoluble trimmingheads journaled in said flier with their axis ofrotation at substantially right angles to the line of reciprocation ofthe aforesaid carrier, a stationary bevel-gear, and intermediate gearconnections between said bevel-gear and the carrying-shafts of thetrimming-heads, -substantially as set forth.

3. In a pie-making machine of the character herein described, thecombination of a supporting-frame, a reciprocable pie-plate carrier, aflier journaled to have rotation in a plane above said carrier,revoluble trimmingheads journaled in said flier with their axis ofrotation at substantially right angles to the line of reciprocation ofthe aforesaid carrier, pinions of the shafts of said heads, a stationarybevel-gear, intermediate combined bevel and straight gears journaled onsaid flier and gearing respectively with the stationary bevel-gear andthe pinions of said trimmingheads, substantially as set forth.

4. In a pie-n1aking machine of the character herein described, thecombination of a supporting-frame, a revoluble flier carried by saidframe, trimming-heads having a segmental spherical shape and journaledin said flier, means for imparting an orbital and rotative movement tosaid heads, and a pieplate carrier adapted to have reciprocation withrelation to said heads, substantially as set forth.

5. In a pie-making machine of the character herein described, thecombination of a supporting-frame, a revoluble flier carried by saidframe, trimming-heads having a segmental spherical shape and journaledin said flier with their axis of rotation at substantially right anglesto the line of reciprocation of the pie-plate carrier, means forimparting an orbital and rotative movement to said heads, and apie-plate carrier adapted to have reciprocation with relation to saidheads, substantially as set forth.

Signed at Chicago, Illinois, this 28th day of August, 1903.
